Preferably this rheostat is of the alinement with the several plates with which ordinary tubular form, comprising a metal it cooperates. The several contact-plates 14 pipe coated with an insulating-enamel, in are each formed with an upwardly-projecting which are embedded the resistance-wires, as arm 21, Fig. 5, by which a connection 22 may is common. The rheostat l is provided with be made with the rheostat, as shown in the o0 lugs 2 2 at the bottom, by which it is secured diagram Fig. l as well as in the plan view to a plate 3 by means of rivets or in any other Fig. 2.

way. For convenience and economy in asas well as the upturned arm of the termisembling I prefer to secure all the parts of nal plate 17, is provided with screws 23, by the device together by means of rivets, as means of which connection may be made with 95 shown. The plate 3 is bent downward at 4, the motonoircuit, as shown in Fig. 1. The

as shown, and secured to that portion is a bottom contact-arm 1O cooperates with a colplate 5, which carries the contact devices, as lecting-bar 24, which is secured to the under will be explained. Obviously the plates 3 side of the insulating-strip 13 by means of and 5 may be formed in one piece. plates 25 and 26, the latter forming one of 100 G and 7 are lugs or ears secured to the plates the terminals for the line-wires and being '3 and 5, respectively, as shown, by means of provided with a screw 27, by means of which which the device may be secured in position theline-wire may be connected thereto. The \within the base of the motor or in any other other line-terminal 28 is secured to the bottom insulating-strip 13 by means of rivets, which connect with the plates 17. The throw of the switch-arm 11 in either direction is limited by means of stops 29 and 30, struck up from the collecting-bar 2%, as shown in Fig. and with which stops the contactspring 10 engages at either end of its movement.

The connections being made as illustrated diagram matically in Fig. 1, it will be seen that when the contact-spring 9 is in contact with the first contact-plate 1% the entire rheostat 1 will be short-circuited and the full line-current will pass through the motor from the terminal 28, plate 17, through the motor, to plate 16, contact-springs 9 and 10, collectingbar 2%, and terminal 26. As the switch-arm is moved to advance the contact-spring 9 successively into engagement with the other contact-plates 1% an increasing proportion'of the rheostat will be thrown into series with the motor. IVhen the switch-arm is moved to carry the contact-spring 9 into engagement with the cut-out plate 15, the rheostat will be cutout and the circuit through the motor will be broken.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a combined switch and rheostat, the combination of a support formed with a recessed portion, a rheostat carried by the support above the recessed portion, contactplates carried by the recessed portion of the support and insulated therefrom, said plates being connected to the rheostat, and a switcharm pivoted to the support and carrying a spring-contact which engages with said contact-plates, substantially as set forth.

2. In a combined switch and rheostat, the combination of a support, a rheostat carried by the support, contact-plates carried by the support and insulated therefrom, said plates being connected to the rheostat, and a switch arm pivoted to the support and carrying a springcontact which engages with said contact-plates, the support being cut away and the spring-contact projecting through said cut-away portion, substantially as set forth.

3. In a combined switch and rheostat, the combination with a support and a rheostat carried thereby, of insulating strips or plates secured to the top and bottom of said support, contact-plates on one of said insulating-strips and connected to the rheostat and secured by rivets passing through said support and insulating-plates, and a switch-lever pivoted to the support and carrying a spring-contact which engages with said contact-plates, substantially as set forth.

4. In a combined switch and rheostat, the

combination with a su pport and a rheostat carried thereby, of insulating strips or plates secured to the top and bottom of said support, contact-plates on one of said insulating-strips and connected to the rheostat and secured by rivets passing through said support and insulating-plates, a switch-lever pivoted to the support and carrying a spring-contact which engages with said contact-plates, a collectingbar on the other insulating-strip and similarly secured by rivets, and a spring-contact carried by the switch-lever in constant en gagement with said collecting-bar, substantially as set forth.

5. In an electric switch, the combination with asupport, a switch-lever pivoted thereto, a series of contact-plates carried by the support riveted thereto and insulated therefrom, each of said plates being provided with a rounded projection or knob, and a contactspring carried by the switch-lever engaging said contact-plates and having an opening or indentation which registers with said projections, substantially as set forth.

6. In a combined switch and rheostat, the combination with a support, a switch-lever pivoted thereto, a series of contact-plates carried by the support and insulated therefrom, each of said plates being provided with a rounded projection or knob, a contact-spring carried by the switch-lever engaging said contact-plates and having an opening or indentation which registers with said projections, a rheostat carried by the support, and integral arms formed on said contact-plates and connected with the sections of the rheostat, substantially as set forth.

'7. An electric switch, comprising in combination a metallic base or support, a lever pivoted thereto carryingan insulated springcontact at one end, insulating-strips on both sides of the base, contact-plates resting on one of said insulating-strips and held in place by rivets passing through the base and both insulating-strips, the holes in the base having a clearance around said rivets, knobs or bosses on said contaceplates over which an opening or recess in the spring-contact engages or registers, a continuous contact-plate secured io the base and insulated therefrom, in electric connection with the said spring contact, and a rheostat the sections of which are connected to said contact-plates, substantially as set forth.

This specification signed and witnessed this 27th day of June, 1900.
